Answer:
A.
Explanation:
Archaea bacteria can live an extreme places.
Answer:
The projections, if they play out, illustrate the potential magnitude of decisions such as the recent one by President Trump to walk away from the international Paris climate accord, in which more than 170 countries agreed to slash their carbon emissions in coming years. Meanwhile, hundreds of governors, mayors and other elected officials have vowed to continue the shift toward cleaner sources of energy.
Hsiang acknowledged that despite the researchers’ efforts to use sound statistical approaches and a wealth of databases, calculating the future costs of climate change is inherently uncertain. Communities are likely to adapt and become more resilient. Industries evolve and relocate.
Delavane Diaz, a senior technical leader at the Electric Power Research Institute, agreed that the study has limitations. For one, it fails to account for how humans will probably plan for and respond to the changing climate. Still, she said, the conclusions provide an important glimpse of the economic risks the United States could face as global warming worsens.
Explanation:
If an animal became extinct such as a rabbit (even tho they abut extinct) then any animal who only ate rabbits would probably become extinct too an that would keep on happening until no more animals in the world unless they adapted to eating other animals
Answer:
Botulism toxin disrupts motor control <u>by blocking the release of acetylcholine by motor neurons. </u>
Explanation:
Acetylcholine is the principal neurotransmitter in motor neurons. If there is no release of acetylcholine from the presynaptic motor neuron, the ion channels will not open. If the ion channels do not open, Na+ cannot enter the postsynaptic membrane to start an action potential. As a result, the muscle can not move.
The ion channels have a specif receptor for acetylcholine. When acetylcholine binds to the receptors, the channels open. With the ion channels open, Na+ can enter the postsynaptic membrane to start an action potential. This does not happen in the presence of botulism toxin since it blocks the release of acetylcholine.
Answer:
<em>1. Context clues
</em>
<em>2. Tone
</em>
<em>3. Word choice</em>
Explanation:
Context clues: Context clues can simply be defined as the hints that we get about the meaning of a word by reading a sentence or sentences related to that word. We can simply infer the meaning of the word by reading the sentence.
Tone: The tone of a sentence helps us to identify what the word in the sentence might mean. For example, if a sentence has a happy tone, we might infer that the word is related to some kind of happy meaning.
Word choice: The word choice refers to the selection of words by the writer. The usage of words by the writer helps us determine what the writer might mean by a word.
